APLUS API8208A
Group Configuration
Voice within each group are combinations of different
fixed memory sections of up to 126 sections. These
sections are the fundamental voice building blocks for
arranging playback without limiting sequencing. This
provides flexibility and allows data to be re-used, beneficial
for applications with many repeated sounds or words.
An example of group configuration is illustrated below:
Group No.
Section Entry
Group 1
Sec 1 + Sec 2 + Sec 3 ……. Sec 109
Group 2
Sec 3 + Sec 2
Group 3
Sec 10 + Sec 11 + Sec 12
Group 4
Sec110 + Sec 10 + Sec 5
Group Configuration
The entry of sections for each group is truly random and
without limitation. However, there is a limit in the total
number of entries for eight groups, which is 992 in the
API8208A It is acceptable to allocate all entries into only
one group or distribute out to other groups. It depends on
how many groups of messages are required.
Programmable Options
Groups in API8208A can have independent options. They
include:
Edge or Level trigger
Unholdable or Holdable trigger
Retriggerable or non-retriggerable
Sequential or Random playback
LED1, LED2, Busy, and Stop pulse are configurable
Four selections in playback frequency
Selections in Triggering
The API8208A can be triggered in different ways, Edge or
Level trigger, Holdable or Unholdable, Retriggerable or
Non-retriggerable. The combinations of the triggering
options provide versatile playback.
By enabling Retrigger, the playback can be controlled in
Stop and Start mode. A trigger on any trigger pin will stop
the current message and start the next message immedi-
ately.
Selections in Playback Frequency
This option provides four choices for each group in
frequency which implies it is possible to have four
different sampling rates in one chip or one sample rate
with a different playback frequency. As a matter of fact,
the available choices are also dependent on the pullup
resistor value at the OSC pin. For example, if the
fundamental frequency choice is F, it can provide choices
in x1, x1-1/2, x2, x3.
Selections in Playback Mode
There are two playback modes, Sequential and Random
in the API8208A If the chip is programmed in Sequential
Mode, messages will playback in the order from Group 1
to Group 8 by triggering the SBT pin. If the chip is
programmed in Random Mode, messages will be played
back randomly by triggering the SBT pin.
Selections in Output Buffer
There are three independent output pins, OUT1, OUT2,
and OUT3, available for several combinations of LED1,
LED2, Stop Pulse, and Busy Signal for each group. The
following table illustrates the four different combinations.
OUT1
OUT2
OUT3
1.
LED1
Busy
LED2
2.
Stop
LED2
LED1
3.
Busy
LED1
Stop
4.
LED2
Stop
Busy
LED1 and LED2 are complemented outputs flashing at
approximately a 3 Hz rate. Stop pulse (STOP) gives a 15
ms positive pulse at the end of the playback for each
Group with option have or do not have the Stop pulse.
Busy is active high and Section dependent but not Group
dependent. Even if same section in different group may
have different output in Busy output. For instance, BUSY
can be high for Section 4 in Group 1 but low in Group 4.
BUSY can be used as a synchronous signal. During
standby mode all three outputs must be low.
Software Support
APLUS provides dedicated software to the customer. With
this tool, the customer can compose their own messages
and configure the chip to fit into their applications very
easily.
